Abstract

The role of dopants on the catalytic activity for the dry reforming of methane (DRM) was investigated on nickel supported on metal doped ceria (Me-DC) catalysts, Ni/Me0.15Ce0.85O2-δ with Me=Zr4+, La3+ or Sm3+, prepared by citric acid synthetic route. The catalytic activity was in the order Ni/Zr-DC< Zr-DC > CeO2. The extra oxygen vacancies introduced by La3+ and Sm3+ were not capable to split CO2. La-DC and Sm-DC showed significant differences in the numbers and strength of surface basic sites. Therefore, other phenomena rule the formation/removal of carbon on these catalysts. The nature of dopants influenced the Ni-supports interaction and the electronic state of the metal catalyst.
